Judging by the fact that all those posts were within a minute of one another, I assume he didn't realize he posted that 4 times. His connection is either slow or it just crapped out and he impatiently hit the "Submit" button 4 times. No harm, I just deleted the duplicate posts.

8-Track: The only tips I can give for this one is to drive smarter, not harder. If you speed your not going to last through all twelve laps. Move briskly, but watch out for walls.

REWARD(S): Monster, Hotring Racer

Blood Bowl: I found the intrsutions for this tournament to be a little vague...remember, DESTROYING THE OTHER CARS IS NOT PART OF THE TOURNAMENT! Focus, focus, focus. In this case, high speed is everything. You must get the red markers before your rivals. Don't get caught in any explosions.

REWARD(S): Bloodring Banger

Dirt Track: The easiest tournament in the game. You'll notice right away that it's the same thing as 8-Track, except with dirt bikes and 6 laps. Note also the huge hill where all of the riders fall off their bikes. HERE'S THE TRICK. You cannot kill them while they're on their bikes; the BIKES are invincible. Instead, wait for them to fall off their bikes at the huge hill...lie in wait over the hill and kill the riders while they're off their bikes. Use a rapid fire weapon like the mini-gun. Simply wait here at the bottom of the hill, hopping on and off your bike so you don't get disqualified, and snipe off and RIDERS that crash on the hill. If your patient enough, they will all crash eventually, leaving you to finish the race without any competition!

REWARD(S): BF Injection

Kick Start: As for this tricky challenge, I would suggest going for the easy points first. Avoid the diffucult red points unless your running out of time and the red one will save you. Utter skill, and not strategy, will win you this one.
